TimefireVR, Inc. (OTCQB:TFVR) (the "Company") today announced investing in the cryptocurrency Ethereum as part of the Company’s shift in corporate focus towards strategic investments in cryptocurrency and potential acquisitions of blockchain technology businesses.

Mining cryptocurrencies isn't something new, but you would require high-end GPUs to actually power these computers to mine stuff like Bitcoin or Ethereum. And that has helped benefit sales in companies like Nvidia and AMD - the producers of these GPUs.

As Bitcoin's value has continued to surge, interest in Bitcoin mining has exploded, but it's struggled to remain profitable because of how energy intensive a process it is - leading to many spending more on electricity than they earn in Bitcoin.
